A method and apparatus are provided for implementing simultaneously connecting of multiple devices in a multi-tiered, multi-directional, enhanced tolerance system with mechanical support structures. A main system planar assembly and an elevated planar assembly share a direct connection provided by a plurality of connectors with no cables. A mechanical support bracket is attached to a top surface of the main system planar assembly positioning and supporting the elevated planar assembly spaced appropriately for accurately connecting respective connectors with respective chassis connectors. The elevated planar assembly includes a stiffening component to facilitate proper spacing between upper and lower levels of respective connectors and tool-less insertion and extraction of the elevated planar assembly.

A cover latch is provided for coupling a blade server cover to a blade server when the cover latch is in a locked state. Embodiments include a locking surface and a user interface; wherein when the cover latch is in the locked state, the locking surface engages a locking surface enclosure of the blade server cover; wherein when the cover latch is in an unlocked state, the user interface is rotated into the blade server and the locking surface is rotated outward from the blade server, wherein when the locking surface is rotated outward from the blade server, the locking surface is disengaged from the locking surface enclosure of the blade server cover; and a rotational limiter hole in the cover latch that surrounds a peg of the blade server, wherein the rotation of the locking surface and the user interface is limited by the rotational limiter.

An enclosure assembly and system are provided for implementing cover-mounted, auto-docking for multiple DASD configurations in information technology equipment. A user selected direct access storage device (DASD) configuration is mechanically attached to an enclosure cover. A cover interposer card is mechanically attached to the enclosure cover and electrically connected to each DASD in the user selected DASD configuration. An electrical connector mates with the cover interposer card as the cover is installed through a sliding motion with a chassis and base planar of the enclosure assembly. A flexible cable interconnect attached to the mating electrical connector is connected to the base planar. The enclosure assembly enables high density, high performance modular server architectures without compromising processor performance or planar electrical architecture.

A cover latch is provided for coupling a blade server cover to a blade server when the cover latch is in a locked state. Embodiments include a locking surface at one end of the cover latch; a user interface at an end of the cover latch opposite from the end with the locking surface; wherein when the cover latch is in the locked state, the locking surface engages a locking surface enclosure of the blade server cover; wherein when the cover latch is in an unlocked state, the user interface is rotated into the blade server and the locking surface is rotated outward from the blade server, wherein when the locking surface is rotated outward from the blade server, the locking surface is disengaged from the locking surface enclosure of the blade server cover; and a rotational limiter hole in the cover latch that surrounds a peg of the blade server, wherein the rotation of the locking surface and the user interface is limited by the rotational limiter.

A caster assembly with a horizontally orientated arm is attached to a base plate of a rack during a travel state and a stored state. A leveling foot with a flat portion and a non-flat portion is inserted through a slot on the arm and a hole on the base plate such that during the travel state, the horizontal orientated arm is in a fully extended position, and during the stored state, the horizontal orientated arm is in a non-extended position.

Forced extension caster assembly

A novel caster assembly with a horizontally orientated arm is attached to a base plate of a rack during a travel state and a stored state. A leveling foot with a flat portion and a non-flat portion is inserted through a slot on the arm and a hole on the base plate such that during the travel state, the horizontal orientated arm is in a fully extended position, and during the stored state, the horizontal orientated arm is in a non- extended position.

An assembly and associated installation method for a server or other electronic equipment enclosure installable into a rack by a single person without adverse tolerance stack-up problems. A mounting bracket is attached to each end of a sliding rail coupled to the server or other equipment enclosure. The mounting bracket includes pins which are inserted into mounting apertures in the posts of the rack to temporarily retain and hold the sliding rail in the rack. Subsequently, a single user can then insert screws or other mechanical fasteners to securely attach the mounting bracket and sliding rail coupled thereto to the rack. The mounting bracket is fixedly secured to the rack and the sliding rail is permitted to move, translate or pivot relative to the mounting bracket to account for tolerance stack-up issues or other abnormalities in the dimensional fit between the server and rack system. The design of the mounting bracket inhibits appreciable vertical translation of the sliding rail thereby providing for proper clearance for the rack space below.
